By reasonof the spring F interposed between the upward eX- tension D2X and-thebody B the position of the cutter is completely determined in whicheverdirection the setting is made by the adjustment of the screw threadedrod E2 which by means of the lock -nut E4 can be locked againstvibration and unrequired displacement.` During the scoring operation thethrust on the cutter is transmitted to the body of the tool through thesaid rearward extension D3X engaging with the bell crank lever E whichis locked against movement by the rod E2 so that there is no likelihoodof the thrust'disturbing the adjustment. Thus the 'directcutting-pressure is transmitted to the body of the tool in such manneras to produce an entirely norma-l upward thrust on the supporting railin whatever position the cutter frame takes. The adjustment for varyingthe depth of cut is effected when the. body and the cutter are in thelowermost or working position in which the milled end of adjustingrodisy presented at C the front of the aforesaid rotatable rail. The

rail A is angularly movable through an angle of 180A degrees and thelongitudinal adjustment of the body B and cutter C is most convenientlyeifected when the cutter C is disposed x above `the said rail when theaforesaid adjusting screw B2 is brought to the front for enabling theoperator to easily make the desired. longitudinal adjustment of thetool. f

By means of the'present invention I provide a scoring tool which is ofsimple construction and which is adjustable immediately by the fingersof the operator without the yuse of any tools and without disturbing thesetting of the tool on the rail, however close the adjacent tools maybe; the adjusting screws for effecting the two settings can be presentedright in front of the operator in the proper position for adjustmentwhichever side of the rail the tool happens to be on, and in the case ofthe setting for depth of cut, the setting and locking is accomplished bya. single screw.

What I claim and desire to secure by Letters Patent of the United Statesis 1. A. scoring too-l of the kind in which the tool body is'mounted onan angularly. movable supporting rail, comprising an adjustvable cutterframe mounted on said body and carrying thecutter, means for adjustingthe frame according tothe required depth of cut and atran'smittingmember interposed between the said cutter frame and the saidadjusting'means7 which 'member forms ay positive stop to` take thethrust due tothe cutting pressure in a direction normal to thesupporting rail.

2. A scoring tool of the kind in which the tool body is mounted on anangularly movable Supporting rail, comprising. a cutter frame pivoted onsaidbody, an adjustable screw in said body, a movable member interposedbetween said screw and the cutter frame to set the cutter frame whenmoved by the screw according to the required depth v adjusting screw inand extending from the front of said body and engaging said member toadjust the position of thepsaid memtit) ber andthe cutter frame and aspring-for maintaining the rear end of said cutter frame against saidmember.

A 'scoring tool of the kind in which the tool body is mounted on anangularly movable supporting rail, comprising a clamping member at therear of said rail for securing the tool body in any desired positionalong said rail, an adjusting screw extending from the front of saidbody to the rear thereof, a rocking member at the rear of said body, acutterv frame pivoted on the front part of said body and a spring actingon the front part of said cutter frame to press the rear end thereofagainst said rocking member.

5. A scoring tool ofthe kind in which the tool ybody is mounted on anangularly movable supporting rail, comprising 'a clampv ing member forsecuring the body in any position along said rail, an adjusting screwextending from the front of the tool `body to therear part, a rockingmember pivoted on saidy b'ody and engaged by the rear end of said.adjusting screw, a cutter frame pivoted on the front part of said body,a projection' at the front end of said cutter frame, and a springinterposed between said projection and said body to maintain the rearend of said cutter frame against the pivoted rocking member. j
